In this paper, the authors propose a new algorithm to find and isolate the nodes which lies about their position in a Wireless Sensor Network (WSN). Also the proposed method enables the sensor nodes to find their location in presence of liar nodes. In the proposed method, a given number of neighbors for all sensors are determined where the number of liars is below a predefined threshold value. The proposed method is evaluated in finding the liars and also the correct location of each node. The minimum error rate on the determination of liars and the location of sensors proves the ability of the algorithm for localization of sensors in the WSNs.
